Agilent 5500 Series FTIR Operation Manual
The 5500 Series FTIR systems use technology known as Fourier
transform infrared (FTIR) spectroscopy, which is the current state-
of-the-art technique for molecular compound identification and
quantification. FTIR uses an infrared (IR) light source to pass
through the sample and onto a detector, which precisely measures
the amount of light absorbed by the sample. This absorbance creates
a unique spectral fingerprint that is used to identify the molecular
structure of the sample and determine the exact quantity of a
particular compound in a mixture.
The heart of the Agilent FTIR spectrometer system is a patented,
rugged Michelson interferometer, field-proven for onsite and mobile
use. This proprietary design is the key to successfully making FTIR
technology compact, lightweight, rugged and field-portable.
The 5500 Series FTIR instruments are controlled using an external
computer running a Microsoft® Windows® XP (32- or 64-bit) or
Windows 7 (32- or 64-bit) operating system. The computer must have
at least a Pentium® IV 3 GHz processor with 1 GB of memory and at
least 40 GB hard disk capacity. The laptop computer is offered as an
option, which provides the flexibility of supplying it yourself or
purchasing from Agilent.
The 5500 FTIR system is available in a number of different sampling
configurations to accommodate the analysis of a range of liquids,
powders, pastes and gels. The optimal use of the various
configurations of the 5500 FTIR system are:
Agilent 5500t FTIR TumblIR System
: For the rapid chemical
analysis of liquids under ambient conditions.
Agilent 5500a FTIR ATR System
: For the chemical analysis of
liquids, powders, pastes and gels. The attenuated total
reflectance (ATR) system is available in single reflection (most
common), three reflection and nine reflection versions. The nine
reflection version has an optional flowcell configuration.
The Agilent 5500 DialPath FTIR is for the rapid chemical analysis of
liquids under ambient conditions that require multiple pathlengths.
